[PATCH v2 0/9] ArmPkg: eradicate and deprecate by set/way cache ops

["Ard Biesheuvel" <ard.biesheuvel@linaro.org>]

This is a combination of v1 'ArmPkg: eradicate and deprecate by set/way cache
ops' and v1 'ArmPkg/ArmLib: ASSERT() on misuse of set/way ops'

As it turns out, there were still some instances of set/way ops left in
the core code, in ArmMmuLib to be precise.

This series fixes ArmMmuLib to perform the appropriate cache invalidation
when populating page tables with the MMU and caches off, allowing us to
get rid of the cache clean/disable/enable sequences which are incorrect
and pointless at the same time.

I have incorporated some ArmLib changes that I posted separately before,
with the end result being that all uses pf set/way ops are gone from the
EDK2 core code, and the routines themselves will now ASSERT() when used
for anything other than managing the caches while the MMU is still off.
(Note that BeagleBoard in edk2-platforms still relies on this)

Changes since v1[s]:
- don't deprecate the set/way ops but make the usable before MMU is enabled
  only
- use a more elaborate sequence for invalidating the page table entries on
  32-bit ARM, to ensure we are compliant with the nooks and crannies of
  version 7 of the architecture.
- incorporate patch #1, which was still pending on the list, and is related
  (its PrePeiCore sibling was already reviewed and merged)

Ard Biesheuvel (9):
  ArmPlatformPkg/PrePi: replace set/way cache ops with by-VA ones
  ArmPkg/ArmMmuLib ARM: remove dummy constructor
  ArmPkg/ArmMmuLib ARM: split ArmMmuLibCore.c into core and update code
  ArmPkg/ArmMmuLib ARM: cache-invalidate initial page table entries
  ArmPkg/ArmMmuLib AARCH64: cache-invalidate initial page table entries
  ArmPkg/ArmLib: move set/way helper functions into private header
  ArmPkg/ArmLib: clean up library includes
  ArmPkg/ArmLib: remove bogus protocol declaration
  ArmPkg/ArmLib: ASSERT on set/way cache ops being used with MMU on
